What are some best practices for handling command-line arguments in PHP scripts?

When handling command-line arguments in PHP scripts, it is important to validate and parse the arguments correctly to ensure the script behaves as expected. One common approach is to use the getopt() function in PHP, which allows you to easily retrieve and process command-line options and arguments. 

// Example of handling command-line arguments using getopt()

$options = getopt("f:l:");

if (isset($options['f'])) {
    $file = $options['f'];
    // Process file argument
}

if (isset($options['l'])) {
    $limit = $options['l'];
    // Process limit argument
}
